There's always so much to learn. It stretches on forever, so sometimes it can get pretty disappointing when you realise that you're never going to get "there", wherever that is. Regardless, I must keep putting one foot in front of the other (I hear the soundtrack from Revenge of the Nerds playing in my head, for some reason).
